Abstract

The utility model relates to a medical appliance, particularly to a colon inflating catheter capable of indicating air pressure condition in a colon, which comprises two hoses and an anal tube, as well as two blocking clamps and an indicating air bag, wherein the hoses and the anal tube are communicated through a tee joint; an inflating nozzle is arranged at the orifice of one hose, an airtight elastic bag is connected at the orifice of another hose, the two blocking clamps are arranged at the two hoses respectively, and the indicating air bag is communicated with the anal tube through a small catheter. The colon inflating catheter with the technical scheme is convenient to use, can be used for inspecting the air pressure condition in the colon in real time, and can safely deflate.

Description

A kind of colon inflating catheter of indicating enteral air pressure situation
Technical field
This utility model relates to a kind of medical apparatus and instruments, is specifically related to a kind of colon inflating catheter of indicating colonic air pressure situation.
Background technology
The patient who suffers from perianal hemorroids, anal fissure, rectal cancer and hemorrhoid usually with the symptom of having blood in stool, in hospital outpatient, usually needs the patient that has blood in stool is checked, with the disease of determining to be suffered from.The method of patient being carried out intestinal inspection has two kinds usually: a kind of is by the anorectal examination apparatus, as the scope colonoscope,, usually very uncomfortable experience concerning the patient because this inspection is invasive, and, very easily cause cross infection because apparatus reuses; Another kind is more advanced CT colon radiography technology, can check the situation of intestinal preferably by the virtual reconstruction of 3D model.Need in intestinal, inject contrast agent during the CT colon radiography, usually adopt and in intestinal, inject the contrast agent of air as the intestinal CT scan, existing inflating method is that gas tube is inserted patient's anal, allow the patient tighten up anus and clamp gas tube, inflate toward the colon the inside by special aerating device then, check.Though existing colon gas tube can be finished the task to the colon inflation, but exist following problem in being to use: 1, in the use, because patient's colon is not quite similar for the perception and the tolerance of air pressure, the patient usually occurs and feel that inflation is normal, and colonic has been inflated too much situation; 2, check to finish when taking out inflating catheter, need earlier intracolic gas to be bled off, the problem that dunghill is gone out takes place in the deflation course easily.
The utility model content
The technical problems to be solved in the utility model is: provide a kind of easy to use, can check the colon inflating catheter that enteral air pressure situation simultaneously can also safety discharging air.
In order to solve the problems of the technologies described above, this utility model provides a kind of colon inflating catheter of indicating enteral air pressure situation, include two flexible pipes and an anal canal, two blocking-up folders and a pilot balloon of connecting by threeway, wherein, the mouth of pipe of one hose free end is provided with charging connector, the mouth of pipe of another hose free end is connected with an air-locked elastomeric bladder, and two blocking-up folders are separately positioned on two flexible pipes, and pilot balloon is communicated on the anal canal by fine duct.
Adopt the colon inflating catheter of the indicated enteral air pressure situation of technique scheme to have following advantage: 1, owing on the colon gas tube, also be provided with a pilot balloon that connects by tubule, pilot balloon can react intracolic air pressure as a linker, the doctor is by by pinching pilot balloon, the air pressure of perception enteral easily, thereby the inaccurate situation of air pressure perception of having avoided the body constitution difference because of patient individual to cause; 2, owing to be provided with elastomeric bladder in the gas outlet of a flexible pipe, when inspection finishes, in the time of need emitting the air in the colon, can be by adjusting the blocking-up folder, close original charging connector, intracolic air and dunghill are put in the elastomeric bladder, the dunghill that this process has avoided traditional colon gas tube to occur easily in deflation course is gone out phenomenon.
Further, in order to improve the ease for use of colon inflating catheter, avoid inserting the colon that inflating catheter hurts the patient, it is dome-shaped that the insertion end of described anal canal is, port is arranged on the dome.
Description of drawings
Fig. 1 is the sketch map that this utility model embodiment inflates user mode;
Fig. 2 is the exit sketch map of user mode of this utility model embodiment.
The specific embodiment
Below in conjunction with drawings and Examples technical solutions of the utility model are further specified:
As depicted in figs. 1 and 2, this utility model provides a kind of colon inflating catheter of indicating enteral air pressure situation, threeway 31 interconnective two flexible pipes 1,2 and anal canal 3, two 12,22 and pilot balloons 4 of blocking-up folder; Wherein, the flexible pipe 1 free-ended mouth of pipe is provided with charging connector 11, the flexible pipe 2 free-ended mouths of pipe are connected with an air-locked elastomeric bladder 21, blocking-up folder 12 is used for blocking flexible pipe 1, blocking-up folder 22 is used for blocking flexible pipe 2, pilot balloon 4 is communicated on the anal canal by fine duct 41, and the insertion end of anal canal 3 is set to dome-shaped, and venthole 32 is arranged on the dome of insertion end.
During use, the anal canal 3 of colon inflating catheter is inserted from patient's anus, and allow patient shrink anus to clamp anal canal 3, then aerating device is connected on the charging connector 11 of flexible pipe 1, take off the blocking-up folder 12 on the flexible pipe 1, pressing from both sides blocking-up folder 22 on the flexible pipe 2, get final product to the colon inflation, simultaneously, the doctor can pinch pilot balloon 4 by hands, the situation of perception inflation is being pressed from both sides blocking-up folder 12 on the flexible pipe 1 after inflation finishes.
During venting, take off the blocking-up folder 22 on the flexible pipe 2, colonic gas and dunghill pour elastomeric bladder 21, behind the air pressure balance, blocking-up folder 22 on flexible pipe 2 folders takes off blocking-up folder 12 on the flexible pipe 1, remaining gas slowly in the colon emitted get final product, the colon inflating catheter is taken out get final product at last.
Above-described only is preferred implementation of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from this utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that this utility model is implemented.
